Can't install update to the latest update.

I have Garmin Experss version 6.18.0.0 on win10 and trying to install the latest version 7.0.1.0. It always gets hung up at NetFx472Reist during installation and this error pops up, "Install Failed, Garmin Express could not be installed on this computer. Try installing again". I already have Garmin Express installed and just trying to update to the latest version. No matter how many times I try, it stalls at the same place during update..
